Final answer:
The passage contains a non sequitur fallacy, implying petting kittens leads directly to their adoption without logical basis for that conclusion.
Step-by-step explanation:
The logical fallacy presented in the passage is non sequitur. The passage implies that petting a kitten will lead to the adoption of a cat, without providing a logical reason for how the initial action leads to the final decision. The fallacy is one where the conclusion doesn't logically follow from the premises. In this case, petting a kitten doesn't necessarily lead to cat adoption, so the claim is a non sequitur. The statement identified as the correct one is C. Statements A and B are not supported because the author doesn't make a generalization about all office workers being depressed, nor does the author use circular reasoning. Statement D is also incorrect since a lack of statistical data about office workers' happiness is not the primary issue with the passage's argument.
